Default (Q)Unmountable_boot_volume

I know this is not a mobile oriented inquiry. But I have a Toshiba Satellite that will not boot PERIOD. No safe mode, no SM w/ CMD, no repair this computer, debugging, and no booting from CD/DVD or USB. I can't even get to recovery mode to run chkdsk /r /f. It hangs up trying to start Windows. Only disc I have is the recovery disc u can burn in Windows, still same thing though.

It tells me I have an unmountable boot volume on a BSOD.Your help would b greatly appreciated, as this is where i turn to in times digital distress
